Unable to add to project or create project from library

Currently using 4.24.2 on a 2015 iMac Retina 5K running Catalina 10.15.3 (3.3 GHz Quad-Core Intel Core i5; 32 GB 1600 MHz DDR3).

After upgrading to version 4.24, I have been unable to either “add to project” or “create project” from library items in the vault. Each time I get an error message of “Install Failed … some of the items could not be copied to the project.” Checking the logs, it looks like all of the files generated the error.

I am able to create projects from scratch, as well as open and run existing projects. I tried creating a project in a previous version (4.23) and got the same results.

I have tried checking all of the settings in Unreal Engine, but cannot find anything that might affect this. I have also tried checking the Troubleshooting FAQ and Answerhub for similar questions, but haven’t found any.

Any advice on the causes of this issue or how to resolve would be greatly appreciated.
